Yes its because of HT.

btw. broke the 1.2V barrier, priming now at 1.184V

Not sure if you posted them Hornet, but can you share a complete list of your bios settings at your current clocks?

[Isepick]

Yes its because of HT.

Learn something new every day. When I get home I'll flash to f4l and start over and not be so impatient ocing my system

Im only trying to find my lowest possible cpu, so ram multi is at 6x.

When i put it to 8x it might need a higher voltage again.

Anyway here are the Bios settings:

Turbo: off
EISTE: off
C4/5/6: off
LLC:on
CPU multi: 20
QPI: 36
Uncore: 17
Mem: 6
CPU voltage: 1.2275 (in windows its 1.2V idle and under load 1.184)
QPI/VTT voltage: 1.355
CPU PPL: 1.86
Mem Voltage: 1.66 (just to be save )
Bclck: 180
SPD: manual (but then everything on auto)
IOH/ICH voltages: all auto/stock

[L0$t Pr0PhEt]

Damn... ah well i dont need them anyway.

Still in the process of finding my 24/7 clocks... i aim for 3,6ghz with HT on at the lowest voltage. (prime/linx stable of course )

Right now im on 1,232V and droping.

Same here but I'm going for 3,8GHz
I'm having a though time keeping the core temp under 70°C.

thanks man. the higher q/v might also cushion the amount of vcore needed as well.

[Hornet331]

yeah i think the same, but ineed a high q/v cause im on 12gb.

everything below that value is a no boot.

12gb's....dang. You into hardcore rendering? that will definitely throw a few spins on your approach.

Im planing to install a 6gb ramdisk, when i have found my 24/7 settings amd played a bit with it.

edit: just got a BSOD after 35min of prime.

Well you cant have everything.

i try to reach 2-3h prime stable and then run some linx. I think i will settle somewhere around 1.22-1.25V

[Hornet331]

I dont mind when my temps get 80°C in prime/linx, cause this apps are the worse case you never will see this temps in real apps.

[FuriousSalesman]

I don't get it. I have 12 gigabytes of ram but I am getting all sorts of problems.
I am running 1600mhz cl8 ram and getting a ridiculous number of errors in memtest. I thought I solved the problem but It keeps coming back. Did you the XMP profile in the ram?

[Xello]

Can someone explain CPU PLL, and QPI PLL, i seen PLL in x48 bios also but never had to change it. I also remember it being alot lower, around 1.5v, back then.

System just crashed fter 7hr 45 mins of prime, how infuriating!

[L0$t Pr0PhEt]

Yeah but I run WCG 8 threads 24/7 so temps can't get too high.

[Hornet331]

Yeah but I run WCG 8 threads 24/7 so temps can't get too high.

I run boinc my self, and prime/linx usually give a 4-5K higher temp then any WUs i have seen.

[Lukee]

Not sure what I am doing wrong here, but I cant get past 175 bclk on my UD5 and 940 to save my life. 175x22 (23 with permaturbo) is rock solid, prime & linpack stable. 180 x 19+, bsods within 5 minutes of prime (getting a lot 0x00000101 and 124s). Current settings are follows, using f4k:

22x175
QPI=36
uncore=13
spd=6
timings are 9-9-9-24 (corsair 1600 rated @7-7-7-10 @1.8v)
LLC=Enabled
Vcore=1.475
QPI/VTT = 1.400
CpuPLL=1.900
QPIpll= 1.24
IOH Core=1.200
ICH I/O =1.58
ICH Core=1.14
Dram=1.8

Raising Vcore all the way to 1.55 does not help the bsods at 180+bclck. Any thoughts and suggestions appreciated...

Edit: Turbo and HT are both on...and playing the EIST function didnt seem to help any.

try these settings.

175 x 23
QPI 44x
Uncore 18x
Mem 8x
ICH Core 1.40
Turbo On, HT OFF

god how i love new tech...

got a new problem, the cpu is stable at 180 mhz qpi with 1.192V but it can't boot with more then 150mhz when 12gb are in the system (it works with 6gb).

It seems the bios s up the ram timings for 12gb, cause it aborts the boot at the post hex 6Bh (Programing the Chipset registers).

Im gona try to give the rams Manual timings and see if it works...

When I run memtest. It says the bandwidth for 6gb of 1600mhz ram is 17000, when I put in 12gb of ram, the bandwidth goes down to 15800.

[Isepick]

Sometimes you just gotta scrap everything you're doing and "reset" lol. Glad you didn't take my comment as a knock

I'd rather learn from others than learn from frying my 940 that cost more than a week's pay I'm always open to criticisms, I am here to learn, and hopefully pass on some of that knowledge to the next guy.

F4L locks my multi in @ 22, I cannot go any lower. So right now I am priming at 22x180 with HT and turbo off. Unfortunately I am running 1.45 Vcore. System won't post under 1.400 and cannot get into windows under 1.425. Was getting BSODS under 1.45 within 10 seconds of linx.

Oddly enough, my temps are way lower than earlier with 22x175 with the lower voltage, though I think having HT & turbo off is contributing to this. My load temps right now are at about 70C.

Gotta run, my woman and I are on our way out to a swinger's club for an evening of enjoyment

well yeah thats expected, 12gb run CR2 and 6gb CR1 (CR=Command Rate).

Btw. can you cold boot with 12gb and more then 150mhz bclck?

I can't get 12 gb stable with 133 Bclck. That's the issue.

[freshy]

who's on bios f4l ? is it any good im still on f4k, almost 13 hours into prime still going @4.137ghz 197 x 19 turbo on ht on

worth going to f4l ?

Some early results on stock air


Love that bandwidth and latency!!

[Isepick]

And on another note, can confirm that mounting a fan on a TRUE Black 120 on the ram side of this board is a no go with my corsairs. Had to mount the fan toward the rear. It is a 120x120x38mm fan in the photo, but a 19mm fan also will not fit. Can also say that the plastic fan door on my Stacker 830 case no longer closes due to the height of the TRUE. I'm gonna have to cut a bit of plastic out to get the door to shut all the way.

[zlojack]

8 Hours done small FFTs. All the settings at Auto except vcore at 1.2v in bios (1.12v under load)

[L0$t Pr0PhEt]

That's quite hot for 1,12v

stock cooler is adequate for stock but nothing more.
